' KNoeKDowN CONTAINER.

Application led June 21, 1921.l Serial No. 479,324.

The object or objects lof-my invention are to provide a new and improved'form of collapsible container of the particular form commonly known as knock-down containers; in which type the .various elements,

when packed in knockidown condition, are

. terioror exterior contour, and while I have shown herein in the various views thereoffrom Figs. lto 7 the broad principle ofl mysaid invention or inventions herein first shown, described and claimed, in which Figures l to 7 a rectangular receptacle is shown, made up of a plurality-.of pieces, all of `which when .in the knock-down condition may be packed within certain ofV the individual parts forming certain of the boundaries of such receptacle when in exvpanded condition, vso that in such knockdown condition it may be bound tightly into a package or packages, and occupy but comparatively little space in trans-shipment to tlie'user; portions of the binding pieces lused to bind and secure the parts in the expanded positiombeing used to bind Ythem when inthe knock-down bundle;V

In Figs. 17 to 2l, inclusive', l; have shown the same broad principle of a knock-down receptacle shown in the foregoing figures of the rectangularjbox or crate form, as applied to a receptacle of the cylindrical central circumferential bellied or barrel form shown. And it is evidentV that ythe broad principle embodied in the two forms ,of rectangular and cylindrical containerherein shown'and described may, without ,(leparting from the scope of the broad claims hereof, be applied to receptacles of innumerable different forms, such -as triangular hexagonal, Octagonal or dodecagonic, or any other suitable form. M

To suchvends broadly considered my said improved knockdown receptaclesare each made up of a suitable number of individual interlocking' separate wall and end or top and 'bottom pieces, which, when assembled in `expandedposition, will form a receptacle ofthe required shape and character, tightly closed and held in. place byexterior bind.

ing-members in such manner that such recepf tacles cannot yunintentionally have their pieces separated one from the other'eXcept by fracture land, dismemberm'ent thereof. And being so constructed that all of such members when'disassembled,-and placed in proper close juxtaposition one to the other, may be boundtogether inone bundle in the case of the boxes and in two in the case of the barrels, by the same binding member or members or a portion thereof, as are used for the binding of the receptacle when in goods of any kind or character. v

' While Ido not ylimit myself vstrictly to the particular form orV `forms of construc-l tion of the several parts makingwup my im-` provedV form ofknock-down carrier-receptacles hereinishown and described, one broad principle runs through all the various? forms thereof toa greater or less degree, and that is that such receptacle comprises two inte- Ygral top and bottom pieces usually and prefexpandedform to be'usedas carriers y*of soV erably, but 'not necessarily, of the single piece form shown, and a plurality of interlocking end-pieces" ai'idside-'pieces or panels,

all'of the end-pieces being preferably, but not necessarily, of one size, and lall ofthe side'pieces rof another size; but both of in# terlocking-joint construction so as to permitl such panels to be .interchangeably inter-'v locked in any desired number to form receptacles ofthe shape or shapes to which they are applicable, in any required plurality;

so that the' same unitary panel members' may be used withdiiferent sized top and* bottom members to form receptacles of many widely varying diinensionsaly widths and lengths and consequently different capacities; and

by having a series of like side and end'pieces built up of an almost innumerable numbershown, described and'claimed inthe follow?v y ing specification, of which the' accompany.-

.ing drawings form a part, in-which similar i letters or numerals of reference designate like or equivalent parts wherever found throughout the Which:-

`Referring to the drawings 1 While l-have shown herein V,only a-rectangular and cylindrical form `of the container, I do not intend in the broad claims hereof to in any manner limit myself strictly to'such forms, as 1 consider that the broad principle of my said inventionorinventions as hereinafter set forth in the broader claims of thisapplication, cover and include receptacles of any other type than the rectangular, cubic-'or cylindrical forms; such for instance even as triangular, hexagonal, octagonal, polygonal, andanyv other forms of receptacle to which the broad 'principle hereinafter pointed out in the claims may be applied.

In practice Vmy receptacle of whateverv form, may be foi'medof various materials,` according to the particular' character ofv the goods to be put'therein for shipment; for certain vpurposes Vthe best materia-l is sheet metal, stamped,piressed, or spun, or otherwiseV formed into the Vproper contoured shapes and sizes; in other cases it may be of cast metal and usually andpi'eferably'in the-case of the barrels the ends are so made of cast metal, but -it isfevident that for certain purposes and uses thev parts maybe Lwholly or partiallyA of wood,`r pressed fiber, cellularpaper board ,or such substances of any suitable form of non-metallic materiall Vmay .be

r' provided with intersecting portions oi slipmost easily described with reference to the' cubic or rectangular forni of container shown in Figures 1-to'16 inclusive.

shown therein such rectangular receptacle comprises in its simplest form (Figs. 1l to 8 inclusive) atop piece 11 and a likebottom piece 12 adapted to receive at either end two comparatively narrow panel members. 13,

and at the sides two somewhat broader panelmembers 14; Awhich may be fof any desired' form of construction but mayl be madeof sheet steel, aluminum, brass orotlier metallicV material; Yare usually and preferably stamped, pressed or otherwise formedy with inwardly or outwardly extending ribs 15,'

which are stampeduor otherwise formed therein to add greater strength and rigidity 'withoutdiminution of the packing space'v within. ln the rectangular or cubic form being now irstdescribed, I have found the barred 'and crossbarred forms' shown in Fi gs;

1 to 5 to be good and 'efhcient strengthening members. l a

lAs clearlyshown inthe drawings, especiallyv in F igs 5 and 6,'the top and bottomV piecesA 11 and: 12 .each comprises an'` interioi bottom late which ma be inteU'ral orin'ade up. of a plurality (jf-parts 'of sheet metal pressed or stampedinto proper form and thereafter assembled and secured togetherl into one homogeneous top or bottom piece vby spot welding or in anylother desired manner. Each of said topand bottoml members alsofcoriipris'ies,` preferably butV not necessarily, upwardly'extending angle or endanges 16,1`andvlike side angesi?, within y'whichfis' located'a secondary inner flange 17"o'ry 16 as the case may-be, according to whether itis an end or a side member. jclearlyshown.

in Figs. 5 and 6 these inner flanges extend Vinward a suflicieiit distance-where the panels join so-that a rectangular 'securing'chamfer or socket is formed toreceive and hold the interlocled panels firmly in position against lateral movement, when the top and bottom arein place, that is, expand or spread out the wall members into interlocked position, soas'to prevent disengagementof the jointuresv or` interlocking portions'ymembers for hoolsof theside or end panel members, 'as

vthe case maybe.y vvAnd this broadprinciple extends' also to "theV circularor Q any other of the various vmodified forms of construction of container. embodying suchbroad principles'.`

V.The end and side 'panels 13 andillare each:

provided with interlocking ljoints, by which they maylee all interchangeably assembled tom pieces of required form, and when se-A curely bound bythe bindiimg members, to be a rigid joint sotdiat no amount of handling or concussion, not ,sufficient ite fracture the panels yor the bottom or .top members, ywill everv serve tocause Ythe disengagement of suchfjoint so as'to disintegrate the receptacle and cause spilling of lits contents. shown in such fFigures 1 to8 inclusive, and

'especially on an enlarged scale in detail in r8, one oit the central joints joining .two of -sueh Vside or Yend panehmembers o r pieces are shown inf-*ull lines in .the :intel-locked :ipoF

sitioin :and in dotted lines. in the releasing position. VAnd each of such `panel I.members carnprisesl a central panel-.or sheet section 18- having kat either end an integrally formed Vhooked securing member 19., interlocking with alike hooked securing 'member 19', formed in like manner by pressing, v.bending, rollingordrawing, in the'adjacent edge ofits coacting interlocking panelmember.

These hooksor jointure lmembers areusu ally ofithesli fvform,shovvnin detail in Fig.V 8,7m the slig .tly modified form show-n in Fig. 16, and ineithe'r formthe. are so made in thecourse of formation of t e panel as to V either slideeasil-y backward .into the position evident that-a variety of corner pieces andV shown in dotted lines -insaid Figs. `8 and 16,V or -toslide longitudinally; 'but in some cases they may lie-made so vnarrow as -toonly ,slide lon ituilinally,` and in .such case the .twoVv hoo s are -of'substantially the same :length so fthat V'the `shoulder 18 abuts against the end 20,.'soas-to locky the joint: against.anyex-` ceptshding-.movement-in the direction of the axesV ofV the two interlocked hooks. It is meansfof y,interlocking may -be used in place of those shown in Fig. 6. In suoli Fig. `6 there areonly two panels oli-each .endand two on each side, and to ,form the Aijoint'one set of such corner abutting panels is provided with theinterlocking Vhoolis 18, with 1 the hooks vin `parallelV plane Vwith .the panel itself, as indicatedunFig. 14: at 18, While the eoacting'panel piece.to form the corner has at one-end .theparallel hook 18, and at the other therightangle hookl22, allot which is .clearly-,shown at fthe corners in Figs. .6

The re uired number of panels 'having been inter ocked'and lit-ted into the bottom piece, thetop 'which is merely :inexact-rep- Leasaj lica of the rbottom piece, is ittedkupon the top of the panel-members after the recepita cle has been filled, and is pressed'down into position and 'the longitudinal securing strap -25 and the cross-like securing strap 26 are placed in position. Such securing straps areshown in detail in Figs. 9 to 13, and the adjustable securing hook member 27 is 'of substantially the shape shown, formed'fin-l "tegrally with or secured to the thin metal Strap eextension `2.7 having at tfheyend the usual downwardly and thin upwardly eX- tending securing hook 1nember 28;, the hook 2S of which, when 1n position, has passed over it the eye end 29 of jone 10i. the inter in Fig. 13, AWhile ythe hook 3x1l of ysuch intermediate securing-strap member 30 is passed through the eye32-ofthe bottom strap meniber 33,.shown in detail in Fig. 1l, which fis contoured as shown to have :the end depressions A34 into which lit the downward veX-v tending iportion's .of the bottoni members, `all' as clearly Vindicated in Figs. l `sto 6 inclusive. Secured to the right lia-nd ,extension iof the securing-straps (Figs, 9 and 10;) and coacting Wit-h the securing hook 27 is the screw yoke-member 35 having a screw threaded orifice 36, Whichfcarriesithe adj-ust able screw tightening-bolt i3? bea-ring upon the left hand concav'cd face of the jhook27, asshown; and looped .-overthe opposite end f of the yoke 35 by a loop 38,-.and spot Welded or riveted so as .tobe firmly secured to said Y yoke, -is the right hand extension of .the u top longitudinalor cross `securing strap, as may be the case, which is provided With a securing hook v28 and 28 voit' the saine shape and contourfas the one attached Vto theedjusting -hook 27. v

And by this arrangement .it will -be seen that vwhen ithe pieces are all assembled together, as shown in Figs. l .to 6 inclusive,` by merely tightening. up `on the ,screws 3,7, Working in the yokes ,35, sufficiently, that the binding straps Will be -rigidly strained to straighteniout the curvesin the end or side =intermediate straps 130, and `the top, bottom and sides ofy the .receptacle thus thoroughly locked against ,accidental `dismembernienty or. collapse.

It Will-be noticed, in Figs. l, 2,3,.4 andY 6, that the securingv straps or .devices referredto are notrarranged at zright angles to oneanother, and the purpose V-of zthis is to addr to thesecurity by locatingthe .members 30, .in each case, in the central lockjoints of the `central vjoint so as to `completelyfill the open portion. of the slip joint Iindicated by' thedotted hook in Fig. 8'; vvand by its presence Ltherein addadditional security .tothe Work of the top and bottom Vpieces in ,preventing accidental slipping oi such interlocking joints. Y

The disasseinblygof course, is. carried ,mediate strap-members 30,.s`howu1 in detail Y lill',

about in the samev manner. W'hen itis desired in theV first instance, upon purchase from the manufacturer, or' upon 'returning tbc receptacle to the owner for further shipments, to save freights, handling, ets. my improved -receptacle is disconnected Vinto more or less complete disassemblement. ,ritter the bottom has been filled with the-end and side pieces 13 and 14 and the side straps 30, the top cover member is invertedA thereon and the two-top and bottom bind'ng ,members 25A and 33 are adjusted into position thereon, as clearly indicated in Fig.17. f'lhe'hooks 2S i of the two adjustable yoke or binding members are then passed through the loops 32 of the bottom straps 33 and by manipulation of the screws 37 of yoke member 35, the said top and bottom members, with the end and side pieces and side straps enclosed therebetween, are securely bound into a relatively small compact bundle or package, for return shipment or storage. Y

v So far as described it will be seen that the corner pieces are in two sections, but in thel detail Figure 15 I have shown a modified form of corner-piece which, forl certain uses, y,

is preferable to theone shown in two pieces, and this comprisesV two securing hooks 1S',

the hooks of'which are' at substantially right vangles to each other and joined together by va substantially cylindrical or segmental in- Y tegral center-member 39.

In Figs. 17 to 20 inclusive, I have shown 'a cylindrical form of barrel-like container which, for certain goods, it is preferable to use instead of the cubic or rectangular or other likeplane faced straight panel forms heretofore described. AsV shown inV the drawings, especially in Figs. 18 and 22, in one ofthe many forms in which such barrel container may be made, the same comprises heads H and H, usually but not necessarily `of stamped or cast metal` formed into suitable form in any preferred way, although in some cases for certain purposes Asuch heads may be made offiiber, .turned out of wood, press-board, or a combination of `metals with i such materials; or of any suitable material rnumber for a great many reasons.

staves 51, as shown inthe drawing, especially in Fig. 18,'are usually and preferably,

but not necessarily, eight in number; as I have found that this is a most convenient Each stave 51 is provided along one longitudinal edge Vwith an outward, and at the other like edge with an inward, securing-hook, subsecuring hooks 18 of the rectangular boxes hereinbefore described; whereby such staves are secured together .in identically the same manner save thatthey are arranged in circle instead of a rectangle as are the panels and corner-pieces of theiirst type.. They are then placed in position inthe heads H and H, as clearly'shown in Fig. 19j, the shape of theislot 50 being such as to prevent side slip Vstantifally `almost precisely similar to the g movement to loosen anddisconnect thehookjoints, such slot being provided for .that purpose with enlargements. into which'th'e hookjoin'ts fit securely when once the staves are in position inthe heads H and H. The

grooves 7 8 in the heads H andH adjacent to the fianges" 79 permit the formation of elongated 'grooves 50 to afford an 'extended securing anchor for the. ends of thel staves 51without requiring the 'chimes 80 ofthe Y barrel unduly to protrude While the staves may be -made of many, almost innumerable, different shapes, lengths and sizes, and especiallyr when made of metal, they are usually and preferably pro--v vided with a plurality of longitudinal stiffening-ribs pressed, rolledY or formed therein in any way, Vas .indicated at 54 of Figs. 18 and 2O',V and such strengthening ribs usually are forced outward, as shown, and are usually` and preferably' two for each stave or peripheral side-piece -ofv such container or barrel. The securing-straps of the barrel type of container are substantially `identical in every respect, except as to size,

with those described .for the rectangular box type of receptacle, as hereinbefore set forth,

vand therefore no further description is thoughtto be needed.V But on account of (the peculiar construction and shape of the various parts of the cylindrical type of conl,

tainer, it has been found best to make two socket members O'struck up or pressed from sheetl metal, and preferably are provided .packages of such containers when in the return' and knock-down position for shipment, `and for this purpose it is necessary to add vnew elements which aretwo stavejsecuring with spring-tongues at either end, yindicated at 61, Figs; 24 and25', which, by their'tension, hold suchstave-securing:end members j in position in the central depressions 52 0f the heads -H and H while in transit; and these can beeasily pried outwhen the barrel is disassembled and the four longit'udinalv`v securing-members 30 disconnected from the bottom and top securingmembers 28 and 33V and secured by their looped and hooked ends,

as the case may be, in the appropriate orifices of the stave securing end members 60into a compact bundle, as shown inFig. 22, while the two securing members 33 and the adjustable V yoke members 35 are secured together around the two heads, all as clearly indicated iny Fig. 21 in detail, when the Ventire device will be in knock-down condition for return shipment. Y

In Fig. 26 and Fig. 27 I show a section and fragmentary plan of a modified form of head or end reinforcement construction one leg'or flange thereof to engage Vwith a corresponding bead or rib `73 pressed or rolled ina head such as the heads H and H',

Fig. 19, or in a cover such as the top and bottom ends or covers 11 and 12, Fig. 2; which angle is secured to the headsl or covers either by riveting or spot-welding, vas at 76, F ig.26. The other? leg or flange of the said angle member 7() abuts and conforms to the inside of the stave Yor panel members, which the exception of the extreme end thereof which` is slightly curved inwardly and which forms the stave or panel directing portion of the retaining slots (Fig. 21) and 16 (Fig. 6). Y

The'slot forming stave or panel overlapping portion 7 4 of the, top 11, bottom 12, or head members H and H, may be reinforced by a Wire rolled into its lower edge, as shown in Fig. 27, and which reinforced edge permits ofremoval of the head or top or bottom members by blows struck upony such edge, without injury thereto.

As shown in detail inFig. 23,-' (inasmuch as the adjustable yoke `members shown in .Figs 9 and 10 are not used in the stave packing but only in the head packing, as shown in Fig. 21), in order that the package of ystaves shown in Fig. 22 can be secured togetherzby longitudinal strap members 30, the stave-securing socket members are provided with the slots 61. vThe said strap members 30, which are used only for binding purposes where the stave or panel is ltoo long for enclosure within the ends or heads, are each provided atone end with a hook portion 31 and at the other end thereof with a loop portion 29. When'the `container is assembled in knock-down state it is securely bound for return` shipment or storage by engaging the hook portion 31 of strap member 30 with the slot 61 in the cap 60. In

Y .order that a constant retaining pressure may be exerted I place between the looped por,- `tion 29 and the slot 61 of the other cap 60 on the opposite end of the assembled knock-` dojwn package, a spring 63. The foregoing description coversthe connection of but one of such retaining strap members, which strap members number four in number in the Vpresent instance, but which number may be increased or diminished as desired.,

Figs.V 28, 29, 3() and 31, are views of a container having end, or ,top and bottom, members and 101, respectively, of different ferent lengths and widths.

Having thus described my invention I claim:

1. A receptacle comprising wall members,}-

hooked formations on the edges Llateral of said wall members, the-hooked formations of adjacent wall members hooking into one another, and means for receiving the end edges of said wall members to expand the hooked formations of said wall members into interlocking position.

2. A receptacle comprising wall members, hooked formations on the edges of said wall members, the hooked formations of -adjacent wall members hooking into: one another, and top and bottom members for expanding the hooked formations of said wall mem bers into interlocking position. Y

3. A receptacle comprising Wall members,

hooked formations on the edges of said wall members, the hooked formations of adjacent wall members hooking into one another, and

vtop and bottom members, there being channels along the edges of said members to re,- ceive the end edgesof said wall members to expand the hooked formations of said. wall members into interlocked position.

"65 i area; and panel or wall members, 105, of dif- 4. A receptacle comprising an end member Y V Aedge portion, said edge portion being bent to form a hook portion, and a second panel piece `provided with an interlocking edge portion to cooperate with said hook portion, said secondy edge portion being offsetxand bent to form a second hook portion, theoffset of said second edge portion beingspaced from the free edge of the hook portion of said second edge portion to form a clearance of at least the length of the first mentioned hook portion in order to permit receiving .f

the first mentioned hook portiondi'rectly lwithout first sliding it thefull length. of the second mentioned hook portion.v
